Alberic I of Spoleto

Alberic I of Spoleto (880-922) was the Duke of Spoleto from 897 to 922, succeeding Guy IV of Spoleto and preceding Boniface I of Spoleto.

Biography
Alberic was born in 880 to the House of Spoleto, a dynasty of Catholic Italians. At the age of nine he was a page of Guy III of Spoleto at the battle on the Trebia River, and he became Margrave of Camerino before murdering Guy IV of Spoleto in 897 and becoming the new duke. Berengar of Friuli recognized him, and Alberic helped him in fighting the Magyars. However, he was opposed to Berengar's imperial coronation, so he allied with Duke Adalberto II of Tuscany against Pope Sergius III. He also allied with the House of Tusculani, marrying Marozia. In 915, he was one of the Christian leaders at the Battle of Garigliano, where he defeated the Saracens of Sicily. He exerted his influence over Rome with the help of the Tusculani, but he was regarded as a tyrant and was murdered in 922.
